Detective Chief Superintendent Russ Jackson, from the North West Counter Terrorism Unit, said: 'We believe Abedi was in possession of this case in the days before the attack at Manchester Arena on Monday 22 May.

'I want to stress that this is a different item than the one he used in the attack.

'We have no reason to believe the case and its contents contain anything dangerous, but would ask people to be cautious.'
